【正文】 中文 2300 字 The status and development trend of Programmable Logic Controller(PLC) Rockwell Automation Control Logic Product Manager, China Region PLC is to improve the productivity of the development of the requirementsdriven. Upgrading difficult to maintain the inconvenience. With the development of electronic ponents, Before and after the 1969 invention of the PLC (Programmable Logic Controller). AB (Allen I. Bradley) is the inventor of the PLC And PLC, one of the family as the use of registered trademarks. AB (Rockwell) since Action of the acquisition), The first is to replace a major role in PLC Relay. Exclusively for the logic of (order) to control functions of a single small memory . However. intheloop regulation. Still need to loop a single instrument or DCS. With electronic technology, control technology, PLC from the simple The development of the digital volume control to a simple analog control and digital volume control with The bination of a partial substitute for the function of singleloop instrumentation. PLC39。s first major application in the automotive production line. With the application of Continuously expand the area of a variety of households in PLC. In order to meet the needs of different Application of the requirements of the needs of families with a strong PLC itself flexibility. Households PLC Factory solution is standardized, modular and work. Input, output signal into 20mA and so on, each signal using. A types of processing modules, each module there are multiple channels, so that the position can not With the size of the system. At the same time, also can reduce the R amp。 D and production costs. Standard Results of a standardized programming languages. IEC611313 In the data structure, program structure, programming language and data exchange, etc. Established international standards, a new type of PLC, including reference to the DCS are marked Development potential. PLC family of work capacity from scratch. Today has been very Powerful. Through the work. Decentralized control can be achieved, reducing installation costs. To improve integration. It is precisely because this flexibility. Users can easily Build their own automated control system. Households PLC is designed for Industrial environment, therefore, reliability and strong antiinterference ability. Ho
